I have a problem of what type of keel bolt material I should use with an oak keelson and an Iron keel. If I use 304 stainless steel the tanic acid in the oak attacks the keel bolt and the stainless keel bolt is more noble than the cast iron and the stainless attacks the iron. In the old days they used a material called Black Iron. I have not been able to locate any black Iron. I did a survey on a 1935 schooner called Dabloon. I had the black iron keelbolts ultrasonicly inspected and were good. Oak Keel and iron keel. Those old guys sure could do it right. They also coated the bolts with red lead. Send me an email if you have the answer Don Huseman 310 4186481 Take a look at monel. Lew |
Have you tried the Blacksmith forums , you don't say how big your bolts have
to be , Iron bolts are not difficult to make they can be made in a charcoal puddling furnace , no rocket science really just Blacksmithing , a rough sketch is ; a small pottery furnace but with a oval well in the bottom bits of scrap steel and heaps of charcoal a buffalow forge blower when the shot starts to melt a steel puddling bar is thrust into the melt , it isn't really fluid but a thick sticky mass , the pudling bar is rolled side to side and the sticky mass sticks to it , when enough material for the job in hand has built up it is withdrawn and a power hammer does the rest in a process called "drawing out" Blacksmiths do this process a lot . Check out "Bramble Bush" forums , I have a book somewhere I will see if I can find it , my email (remove all the nospam) Cheers Ian in Bendigo Lat. 36;44;22 S Lon 144;19;47 E -- A fine beer can be judged by one sip , but it's better to be sure "Lew Hodgett" wrote in message ink.net...

Exotic topic, any more - sounds like wrought iron toys from a scrap carriage would do it, skipping the puddling step. I couldn't give a collection of parts from a trap away a year or two ago. Still mouldering in the long grass.... Brian Whatcott Altus OK |

Brian Whatcott Altus OK Brian I don't think so , the bolts I have seen on cast iron keels are usually one inch plus !! now if the bolts in your trap are that big it either comes from Texas or it's a "Road Train Trap" !!!!!

Cheers Ian in Bendigo Oz Hehe...true enough traps don't use one inch bolts - but they do, I mean did, use wrought iron, which is forgeable into a decent black bolt - skipping the puddling stage Brian W |
